So I just bought, downloaded, and started using BeerTools Pro and for the life of me I can't figure out how to scale recipes. I have a recipe for a 5 gal batch and want to try a smaller batch first. I entered all the ingredients for the 5 gal and want to scale it down.

Can I do this using BeerTools Pro or do I need to formulate the recipe online in order to scale it?

To scale a recipe, check the box next to the "Final Volume" value. Select "scale" in the pull down menu next to the check box, then change the "Final Volume" to the volume you want. The recipe will scale accordingly.
